ROCK SPG prefixes in area code 307
NANPA records 17 assigned NXX blocks to rate center ROCK SPG in area code 307, 3.4% of the 499 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 8 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WY (5), UNION TELEPHONE COMPANY (3), QWEST CORPORATION (3). The earliest assignment on record here is 2001-03-27 and the most recent 2024-05-06. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 406 – overlay codes cover the same geography, so a rate center is served by all of them.
